From 7c81582c0bccb4757186176f0ee12834597066ad Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Fri, 9 Jun 2023 11:28:04 +0200 Subject: [PATCH] mfd: stmfx: Nullify stmfx->vdd in case of error Nullify stmfx->vdd in case devm_regulator_get_optional() returns an error. And simplify code by returning an error only if return code is not -ENODEV, which means there is no vdd regulator and it is not an issue.
